or cap of comparative simple construction, composed of a minisive andsimple threading of caps; may be both removed and tive side pressure ofthe cap; to provide a construction available either side, which a sidepressurebreaks of parts andthereiore inexpen to manutacture; to

to prov de a cap which avoid the replaced by a posh thuinb against theself lifting and sell scaling for opening from when the cap is sub'ectcdto the'seal bylifting the cap, provides clearance for the cap in tippingfrom the container and clearance again in replacement thereon; toprovide. a cap construction which may be readily and conveniently openedand closed by one hand operation to provide a construction which at alltimes firmly holds the cap both in open and closed position;

to provide a construction which adequately distances the cap froin the,outlet when in open position; toprovide a combination double seatedandstruction; to provide a construction adapted to lift the cap andthrow it ofi center dur ng the opening operation;

to provide an 1111-- .proved spring construction adaptable to function'as a hinge and a specific and positive anchor designed to make ma s ofthe spring hug the orifices into which they are fitted;

lVhile We have illustrated and described a preferred construction forcarrying our invention into effect, this is capable of variation ormodification without departing, from the spirit of the invention. Wetherefore do not wish to be limited to the exact details of constructionherein. set forth but desire to avail. ourselves of such variations andmodifications as come within the scope of the appended claims.

Having thus described our invention we claim as new and d sire to ,ecureby Letters Patent of the U12 l States of America:

1. In combination With a receptacle having a hollow body and anapertured neck ex teiidiug thercfro";, the outer edge of said neck beingbevelled and at its top flat, shouldcrs on opposite sides of said neck,transversely disposrid sockets in said shoulders, a cap having recessestherein the inner edge of which is shaped to seat and seal upon saidbevelled cdgre, and having a flat extreme inner surface teeth upon saidshoulders adapted to cooperate with said cap, a casket on said flatinner surface adapted to nt against the top of said neck when saidbevelled edge is sealed, and a wire loop extending from the neck overthe cap, said loop having; singularly arranged pivot pins with a burr onthe ends thereof adapted to fit into said transversely disposed sockets.

In combination with a receptacle having a hollow body, and an aperturedneck extending therefrom, the outer edge of said neck being bevelled andtop flat, shoulders on opposite sides of said neck, transversely dis-'rosed sock, in said shoulders, a tooth extending from each shoulderdesigned to engage and mesh with prongs on each side of the cap nextmentioned, a cap the inner edge of which is shaped to seat and seal uponsaid bevelled edge, and having a flat extreme inner surface, a gasket onsaid flat inner surface, adapted to fit against the top of said neckwhen said bevelled edge is sealed, said cap having; extending thei rompair of prongs adaptable to mesh with said tooth, and

a Wire loop extending from. the neck over the cap, said loop havingangularly arranged pivot pins with burr on the ends thereof adapted tofit into said transversely dis posed sockets.

3. In a device of the kind described, a container having a hollow bodyand anapertured shouldered neck, transversely disposed sockets'thcrein,a double seated cap adapted to fit upon said neck, said cap havingspaced prongs extending therefrom, a wire loop having angularly arranpivot pins with a burr on the ends thereof, adapted to lit into saidtransversely disposed sockets and secure the cap to the neck, teethprojected from the shoulders on the container shaped to mesh andfunction with said pron gs to lift tl c cap and throw it off center asside pressure is applied during the opening operation.

at. In a device of the class described a container having hollow bodyand an apertured neck, shoulders upon said neck, a cap adapted to fitupon said neck, said cap having spaced prongs thereon, means forpivotally securing said cap to said shoulders and teeth projecting fromsaid shoulders adapted to mesh and cooperate with said pron, ;s to liftsaid cap and throw it oil center asside pressure is applied during theopening oporation.

5. In a device of the class described a container having a hollow bodyand an apertured neck, shoulders upon said neck, a cap adapted to fitupon said neck, said cap having spaced prongs extending therefrom, awire loop securing said cap to said neck and teeth projecting from saidshoulders upon said container adapted to cooperate with said prongs tolift said cap from said aperture in said neck.

In testimony whereof we affix our signatures.
